....3 Finally, Phase 2 is recomputed (i.e. residue based and region based analyses) as speculative profileguided schemes (Section 3. 2) Additionally, regionbased analysis may now assume that contents of memory cells will not be used as memory pointers (i.e. corresponding descriptors are mapped to [14]) The resulting data and region based information from the previous phase is the unsafe aliasing information. Memory disambiguation for a particular pair of memory references is then applied incrementally, as can be seen in Figure 4. Note that a new relationship is used for those pairs of ....
....speculative residue based alias analysis (Section 3.2) PGReg The profile guided speculative technique is applied to the also speculative region based method. PG Reg 0 Corresponds to the previous analysis method, but contents of memory cells are assumed to not be used as memory pointers [14]. Table 1. Description of alias analysis methods for memory disambiguation. its basic block execution profile) Any basic block whose execution count is at least N is then said to be hot with respect to the threshold . For example, given = 0:95, the hot basic blocks of a program consist of ....
